NEC Commercial Electrical Practice Test

The phrase "in sight from" indicates that one piece of equipment shall be visible and no more than what distance from the other?

1. 25 ft

2. 50 ft

3. 75 ft

4. 100 ft

The correct answer is: 50 ft

The phrase "in sight from" is commonly used in electrical code and practice to establish the visibility requirement between different pieces of equipment. In the context of the NEC (National Electrical Code), this requirement ensures that any operational safety features or controls of one piece of equipment can be easily monitored and accessed from the other piece of equipment. The correct distance associated with "in sight from" is 50 feet. This standard helps promote safety and accessibility, allowing an operator to quickly assess the status of equipment without needing to walk long distances, thus reducing risks associated with operating equipment in potentially hazardous environments. The rule aims to maintain a practical line of sight, ensuring that equipment can be managed efficiently and effectively within a given area. Understanding this distance is crucial for proper installation and adherence to safety protocols as outlined in the NEC.
